Although I don't have much to add, I am curious as to what your resting voltage is when sitting overnight at low temperature with the truck off? As long as the batteries are charged, they shouldn't freeze. But with the high initial voltage, it makes me think that the amperage is near zero until the electrolyte "gets going". Almost like the higher voltage is the alternators unloaded voltage. As long as the battery cases don't start to bulge from excessive electrolyte outlasting, then I would say you are ok. Block heater on a gasoline motor? Yeah that's cold. I am not sure at what point a battery heater is needed.

Nice looking set! Do you sell the clamps separately?

It would work better if you can place it close to the amps. -

Sure square waves exist in recorded music but it is over the whole spectrum mixed with a multitude of other waves. The real question is when a driver has to reproduce a signal that is in a very narrow band and the signal is a very low frequency and it is clipped from the source, like the head unit is maxed out. What happens then? Sorry if I assumed the original question was aimed at the subwoofer usage. This is where people are most likely to run into problems.

Ok so I am just trying to figure out where the logic for #1 comes from and where it went wrong. A sub coil is cooled by its movement, and moving less would cause more heat, along with more "power under the curve" causing more power to be disapated which can be hard on a coil. So at some high power level and low frequency that would lead us to believe that #1 is true?
